Erwin Rommel was always considered one of the ‘good’ Germans of WWII. He was a brilliant tactician, loved by his soldiers and respected by his enemies. He was forced to commit suicide, because he was suspected to plot against Hitler.
Overall the German military establishment utterly failed to stop Hitler in it’s tracks. They are - with a very few exception - a classical bunch of non-thinking military figures. Just following orders!
Although it might weaken a military, but a modern country needs ‘thinking soldiers’, critical of their leaders, critical about war and the reasons for it. No fatherland, no motherland, no religion, no dogma is worth dying for.
You should put your life for a good reason on the line.
